Manoeuvring the uncoupled
machine
DANGER
Special caution must be exercised during ma-
noeuvring work with released service brake
system since the crop protection sprayer is now
braked solely by the shunting vehicle.
The machine must be connected with the shunt-
ing vehicle before the releasing valve on the
trailer brake valve is operated.
The shunting vehicle must be braked.
NOTE
If the air pressure inside the air reservoir drops
below 3 bar (e.g. because of several actuations
of the releasing valve or leakages in the brake
system), the service brake system can no longer
be released via the releasing valve.
To release the brake:
¾
completely fill the air reservoir.
¾
completely drain the air reservoir.
Parking
DANGER
Serious accidents caused by the machine roll-
ing away!
¾
Park the machine on a flat, paved surface.
¾
Secure the machine with wheel chocks before
unhitching.
¾
When unhitching machines with pneumatic
brake you must always disconnect the red
connection (supply line) first.
WARNING
Risk of accident by uncoupling the crop protec-
tion sprayer with the folding boom unfolded!
Negative drawbar load can cause the machine
to tip over!
¾
Always park the machine in transport position!
NOTE
¾
Clean the machine and prepare properly
before parking it for an extended period; see
chapter Care and Maintenance.
